Is there a good explanation of those rules that a non lawyer can easily understand?

To me, I'm thinking you'd have provenance on an earlier image. And for some, fairly clear identifiers.

This card with PSA serial number X was shown in this image when it was offered on x date by this particular seller.
Theres a unique wood fiber inclusion visible just here further identifying the card.
That image is X dpi, making that fiber x distance from the nearest edge


This image is a new image created on x date, and at the same dpi as the original. Note the unique fiber inclusion is now Y distance from the nearest edge.

This is the actual card, as shown.

That could be done for all edges and overall size.

Would it not be allowed?
